Interesting but it assumes the teens will bother to look at it.

We use a WhatsApp channel for our family to manage breakfast meetups and who needs what from the shops or the pharmacy (they are on our healthcare plan) and general conversation about events or troubles and parental advice in their lives.

One kid live on her own with her bf a few minutes from us but she can't drive so we sometimes have to pick her up from work.

It gets muddled but works for us as the rule is no pet photos unless it is very cute (cat with a dustbin cover on his head) or inspirational daily quotes.
